英文摘要Secondary recrystallization Goss texture was efficiently achieved in rolled, binary Fe81Ga19 alloy sheets without the traditional dependence on inhibitors and the surface energy effect. The development of abnormal grain growth (AGG) of Goss grains was analyzed by quasi-situ electron backscatter diffraction (EBSD). The special primary recrystallization texture with strong {112}-{111}< 110 > and weak Goss texture provides the inherent pinning effect for normal grain growth by a large number of low angle grain boundaries (< 15 degrees) and very high angle grain boundaries (> 45 degrees) according to the calculation of misorientation angle distribution. The evolution of grain orientation and grain boundary characteristic indicates that the higher fraction of high energy grain boundaries (20-45 degrees) around primary Goss grains supplies a relative advantage in grain boundary mobility from 950 degrees C to 1000 degrees C. The secondary recrystallization in binary Fe81Ga19 alloy is realized in terms of the controllable grain boundary mobility difference between Goss and matrix grains, coupled with the orientation and misorientation angle distribution of adjacent matrix grains.
